On the internet to see someone said Avplay can play streaming media, then take over to use, and found that anyway it is to the MP3 cache after the completion of the play, the audio long to wait, for the M4A format is better, MP3 is not, and this experience is very poor. So on the Internet to collect methods, and found the Freestreamer library can achieve edge caching while playing MP3 files, online data is relatively small. Here's a general summary. My code doesn't write well, just give you what
The essence of swarm and k8s are container orchestration services.They can abstract the underlying host, and then start the application from a built-in image and eventually deploy it to a host on a docker basis. Which scenario should be chosen as our container cloud service? I think k8s (kubernetes short) and swarm compared to MySQL and SQL Server comparison, the former lightweight, implementation fast, in order to achieve core functions, more suitable for small-scale deployment, the latter is e
One, the response chainIn iOS development, you encounter various action events that can be used by programs to respond to these events.First, when an event response occurs, you must know who is responding to the event. In iOS, the responder chain responds to events, all event responses are subclasses of Uiresponder, and the responder chain is a hierarchy of different objects in which each object is given an
three main cases where UIView does not accept event handling:1) Alpha 2) userinteractionenabled = NO3.hidden = YESThe following comes from the network:Responder chain Concept: When the iOS system detects a finger touch operation, it packs it into a Uievent object and puts it into the event queue of the currently active application. The uiapplication of a singleton takes a touch event from the event queue and passes it to the uiwindow of the Singleton, UIWindow object first uses the Hittest:with
application. The event is then passed to the priority object cyclically by the event. Priority response objects are the objects that interact with users when an event is triggered, such as button objects and view objects. If we write code to let the priority responder handle this type of event, it will process this type of event. Responder after an event is handledThere are two options: 1. Discard it; 2. P
event is processed. Normally he will send it to the main window, and the main window will then pass the event to an initial object, which is touch eventsThe event is first sent to the most appropriate object for processing. For touch events This object refers to Hit-test view, which refers to the first responder for other events.UIKit first sends the event to the object which is best suited to handle the event. For touch events, this object is the Hi

PrefaceWhen we are using tools like this, click Sweep to open the QR Code scan view. When we clicked on the screen, the iphone OS got the user "click" Behavior, the operating system wraps the information containing these click events into Uitouch and uievent forms, and then finds the currently running program, looking for the object that can respond to the event. Until there is no responder response. This search process, called the event's response ch

13.1 event Overview 13.2 touch events 13.3 gestures 13.1 event Overview An event is the object that the system continuously sends to the application when the user's fingers touch the screen and move on the screen. The system passes an event to an object that can be processed according to a specific path. In iOS, A uitouch object represents a touch, and a uievent object represents an event. The event object contains all the touch objects corresponding to the current multi-point touch sequence.

Themselves.nbs P For the manual method, a server must is used as a launch pad for the automation and would also be used to work/script with The Netscaler. Also Note that I ' m just calling it a PKI server and that's not something so you'll see when researching let's Encrypt, And I would guess that this kind of goes against their vision. The idea is automation of these processes. By adding a intermediate server into the mix, we are definitely complicating matters. In an ideal world, the Netscale
